APPARATUS FOR TREATING TIMBER.

Application inea' February 2o, 1917.

To all wwm it may concern.-

e it known that I, ERNEST F. HART- MANN, a citizen of the United States,residing at T e present invention paratus for treating timbers with asuita le wood ter and of irregular contour. The present have devisednovel and improved means forhermeticallv joint between the the sides otthe pile.

luther objects ot' the invention will become apparent from tion whentake-n in connection with the accompanying drawings. which show the pferred embodiment ot' the invention, and in which` Figure l shows theupper end of a pile with the apparatus mounted on the same, shown insection taken along line 1`l of l'g. 2;

is indicated at l. `ldapted to encircle the pi e a convenient distancefrom its upper end, is an adjustable collar 2 separate sections adaptedto be detachably fastened together by shown in Figs. 4f and 5, thecollar are like Z bars in cross section with inner wall 4 having pointedprojections or picks 5 for being embedded into the timer, a horizontalshoul er or seat 6 for supporting the joint sealing material hereinafter described, and an outer vertical wall 7 for retaining said sealingmaterial on the shoulder. g end said sections have suitable perforations9 is .shown at t e collar and with a curved O for resting againstthcwall ar.

Located above the collar i) embracing member a head l) with dependingadapted to surround and embrace the upper-end ot the shown, thetimer-embracing member is shaped like a elvlindrical cap member forfitting over the top lower end of ot a cvlindrical pile.

l prefer to employ plaster ofParis for -the material and for thispurpose mto the collar 2 around the pilc while in a plas ic condition,so as to l all crevices andgfopeningsf1 the space within the cap'member.Any crevices too large for being automatically plugged up by 'theplastic plaster of Paris may be stuffed with paper or cotton waste tosupport the plaster until it hardens. rlhe plaster of Paris may bepoured into the space between the collar 9. and the pile, either beforeor after the cap member is mounted.

The cap member may be firmly locked to 'the collar preferably by meansof a series o bolts 23, evenly distributed around the pile, and havinghooks 24 at their lower end for engaging beneath ribs Q5 at the outer'edge The upper ends of 23 extend through enlarged perforations Q in thehead 12. and are screwthreaded for receiving hand-wheel nuts 27 whichmay e turned for tightening an the bolts drawing up on said bolts. 28 isa grasping ring upon the head of the cap member, whereby the same mayThe operation of the apparatus is as follows. After the plaster of Parisin its liquid state is poured into the collar 2 and between the pile,and the cap member and the latter is secure y locked to the collar asabove described, the plaster of Paris is allowed to set and harden so asto make a substantially hermetically sealed joint between the sides ofthe timber and 13 of the cap member. Thereupon the wood-treating fluidmay be introduced through 'the pipe 1 der pressure, and the treatmentcontinued to impregnate the timber as far as may be desired. After thetreatment is finished, the space between the cap member and the ile maybe drained of wood treating fluid out through the pipe 15. The collar 2may loosening the bolts 23 d to p away its walls 13 from the plasterseal. The lower ends 14 of the walls 13 are flared outwardly as shown,so as to facilitate this breaking away from the plaster seal.'

It will be obvious that a portion of a pile or timber intermediate theends may e similarly treated, in embracing memb cylinder open at eachend, be closed around the timber by means of a detachable and adjustablecollar as above described.
